SPRAYING-MACHINE.

I To all whom it may concern.',

' chines, of Whic citizen of the United Be it known that I JOSEPH D.WALLACE, 21 States, and a resident of the city and county of Champaignand State of Illinois, have invented certain new and useful Im rovementsin Spraying-Ma ii the following is a specification.

This invention relates to portable spraying machines, such as are emloyed for the purpose of pro erly distributing a fertilizer or' aninsectici e, or other liquid compound for other purposes, over lawns,fields, gar dens, parks, boulevards and the like. Such machines areusually suitably mounted upon wheels and are generally adapted to bedrawn b horses. Apart from delivering the liqui in the form of a spraywhich is properly distributed, it is desirable to cover as much groundas possible at each operation, wherefore it is desirable to employ inconnection with the portable frame, the storage tank or reservoir andthe force pump, a pairof arms projecting laterally from the machineandsupporting delivery pipes from the pump, said delivery pipes be,- mg:provided with-aplurality of spraying nozzles whereby the path covered bythe spraying devices will be of the greatest possible area.

It will be apparent that where longrprojecting arms are employed, if thesame are rigid, two difiiculties are encountered; first, that of drawingthe device into any suitable inclosure or through any ordinary door oropening for the purposes of storage, on account of the excessivedistance between the ends of the two arms, and, second, that indistributing the desired compound over a field or through an orchard,obstacles are likely to be encountered, such as, a tree,

and much time lost in .order to get aroundstump post, the edge of thebuilding or an animal, in which case, if these arms were rigid, one orthe other thereof would very likely be broken, and under anycircumstances great care would have to beexercised any obstruction of apermanent character andstill treat the ound or the plants in theimmediate vicinltythereof. I

The object. of the present invention is the provision of a portablespraying machine equip d as suggested with longv arms, and there orecovering a very wi e ath in transit, said arms being provided wit meanswhereby, first, they may be folded back Specification of Letters Patent.Application filed February 13, 1909.

against the machine, when not in use, and thus bring the extremedimensions of the machine within ordinar compass, and, sec- .ond, whilenormally he d in their extended or projected position, will,independently swing or fold rearwardly when an obstruct1on of anycharacter is encountered. Incidental to the above, I have in view aportable spraying machine which is simple in construction, dependable inoperation, comparatively cheap in cost, and which will eover the largestpossible area in its opera- Mv invention will be more readily underbyreference to the accompanying drawm s, forming part of thisspecification, 1n whic i,

Fig. 1 is a rear elevation of a machine embodying my invention with thearms thereof extended; Fig. 2 is an enlarged perspective view, partlybroken away, of one of the arms, in its extended osition, showing thepreferred manner of rigid portion thereof to the frame of the machine;Fig. 3 is a top plan view of the arm shown in Fig. 1, and Fig. 4 is anenlarged top plan view of the rear portion of the body of the machine,showing one of the arms folded back against the rear of the machine.

As suggested, I prefer to mount the device upon a suitable frame 7 whichis pref-.

erably mounted upon four wheels, of which the rear wheels 8 and 9 areshown in Fig. 1.

Upon this frame is mounted the storage or' supply tank 10 for the liquidemployed, below which (not shown in the drawmgs inasmuch as it forms nopart of the present invention) is located the pumping mechanism, whichis generallydriven from the rear axle or from one of the rotatingwheels.

Suitably carried by the frame of the machine, at the rear thereof, isthe fixed horizontal supporting bar 11 carryinga vertical pon theseposts 1s mounted the fixed or rigid middle portion 13 of the supportingarms, this rigid portion 13 being. subject to vertical adustment uponsuch'posts 12 in any suitab e manner.

I Suitably fastened to each end of the rigid middleportion 13 of thesupporting arms, is a pair of plates the upper 14 of which'is laterallyextended inboth directions to provide the longerg armvlo on one sidethereof and the shorten-arm 11 on the other side attaching the to theend of the arm 22. It willv be apparent that this construction permitsof the swinging of the arm 22 in a horizontal plane about the pivotprovided. by the hinge-pin V 18. The length of each of these armsq22renders it necessary that they be vertically supported, the hingeconnection with the beam 13' not being suficient for this purpose. Forthis reason, I'prefer to elongate the hinge-pin 18 to form a post to thetop of which are-secured the tie-rods 23 and 24,

.the former secured to the beam 13 and the latter to the swinging arm 22and supporting said arm. The tie rod 24 has pivotal connection with thepost 18, and having a common center will swing with said arm 22 when thelatter is moved in a horizontal direction. r

The arm 22 is normally retained in its extended position by. means of adevice which comprises the arm or bracket 15 and the brace or tie-rod 25secured to the beam 13'and the end of saidarm 15. Pivoted to the arm 22at 43, is the hook-link 26, which corresponds to the link 27correspondingly pivoted near the end of the arm 22. To the other endof-these links is pivoted thebar 28, and these links are so disposedwith re lation to the arm 22 that pressure against the bar 28 in thedirection of said arm will cause saidlinks to -turn upon their pivots assaid bar 28 is forced toward the arm 22. In thehookiwith which the link26 is provided, is inserted the hooked end of the rod 29, the otherend'of which is securedto the end of the arm 15 through theinterposition of a tension spring30. lhis adjustment is such-that whenthe bar 28 is forced toward the arm22, the hook in the link 26-willbewithdrawn from the hook'in the end-of the rod 295, and the arm 22 willtherefore be free to swing ina horizontal plane. The tension of thespring 30 is suflicient to normally- 4 m u s retain'said'arm 22 in itsextended position,

the function'of this spring being primarily "to allow :tor a timeelement during the short cried that the' ,bar'28 is operating to un ookthe rod :29.' v From the reservoir orj supplyfitank 10 leads a' suitablepipe. 31 communicating, through the couling 32 with branches" 33 and 34dl upon thebeain 13. Near the ends of said beam 13, these branchesterminate in hose, 35 and 36, res ectively, or other flexible tubing,which form flexible connections with the extensions-Maud 38 of saidbranches, respectively, supported upon" the swinging erases arms. Iprefer that the pipe shouldbe secured to the arm by means of suitableclamps 39, and .at regular intervals, along the whole length of pipe,are provided a series of spraying devices 40 which may be of anydesiredform and character.

It will now be apparent that arms of coinparatively great length may beemployed, thus enabling me through the employment of my device to covera very wide path with a single trip of the machine. It will furthermorebe apparent that if an obstruction is encountered whichwould normallytend to break on distort either of the two extended arms, suchobstruction will first impinge against the bar 28, forcing the sametoward the arm 22 and through the links operating to unhook the tie rod29 and permit said arm to swing on its hinge and thus clear theobstruction. Furthermore, it will be apparent that through theoffsetting'of the hinge-pin 18 from the vertical plane of the arms, thelattermay swing through an arc -of approximately 180 andthus fold backagalnst the rear of the machine, as shown in.

.[s a means of insuring unhooking or unclasping action whenthe bar 28 ismoved -unclasping due tojari'ing of the machine.

l urthermore," the pin 42 acts as a stop to prevent movement ofv thelink'26 .to the left (Fig. 3) beyond its normal. point as shown in thedrawings.

lllany modifications of minor details of my improved spraying machinewill doubtless readily suggest themselves to those skilled in the art towhich it appertains and I therefore do .not desire to limit myinventionto the specific construction herein shown and, described,

I claim as new and desire to secure by Letters Patentr 1 1. In a deviceof the character described, the combination, with a portable frame, of arearwardly swinging arm normally pro.- ectmg laterally fromsaidframe,means for locking said arm 'in its extended position, 1

In testimony of the foregoing, I have hereunto set my hand in thepresence of two witnesses.
